eljefe, in the case of Netflix the do. The problem is Verizon refuses to update their infrastructure to accept the traffic that the providers are trying to pass through to the Verizon customer who are demanding that traffic.
Traffic flows through the internet fine from Netlix to the transit provider until it gets to the handoff to Verizon. The bottleneck is that Verizon has dropped the ball on keeping it's infrastructure upgraded and cannot handle the amount of traffic that the transit provider is trying to hand off.
The reasonable solution is that Verizon should upgrade it's equipment at the handoff point to accept the traffic that Netflix is trying to give them.
